Answer:
√3681
Step-by-step explanation:
D= √(30+30)^2+(19-10)^2
D= √60^2+9^2

D= 3681
Answer:

Step-by-step explanation:
If the point Q that is located two over three the distance from point P to point R, then PQ:QR=2:3.
Use formula to find the coordinates of the point Q:

In your case, P(-2,7) and R(1,0), then

B. Because the divisor, 4.2, has only value in the ones and tenths places, so we only have to multiply by 10 to get to 42, which is the whole number you need.
The actual distance between the cities is 50 miles
